TIRE-TIGI-ITENER.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed. May 8, 1909. Serial No. 494,830.

T 0 all whom it may concern:

Be it known that I, GEORGE A. RYAN, a citizen of the United States,residing at Amarillo, in the county of Potter and State of Texas, haveinvented certain new and useful Improvements in Tire- Tighteners, ofwhich the following is a specification.

My invention has relation to tire tighteners, its main object being toenable a Wagoner to place the required tension upon the felly of a wheelto hold the tire thereof rigidly against the outer surface of saidfelly.

It is commonly known that the metal tire of a wheel, due to the constantpressure upon it, gradually expands until it becomes loose upon thewheel, which it protects.

With the aid of this invention the tension upon said tire may beincreased in proportion to the amount of the expansion of the metal.Therefore it is obvious that the life of a tire upon a wheel embodyingmy invention, will be much longer in duration than ifmy device were notemployed.

With these and other objects in view my invention consists of the novelconstruction and arrangement of parts as are hereinafter described inthis specification, and illustrated in the accompanying drawings, whichare not drawn to any particular scale, and pointed out in the appendedclaim.

Referring to the drawings: Figure 1 is an elevation of a wheel embodyingmy invention. Fig. 2 is a central, vertical, segmental, sectional viewof Fig. 1. Fig. 3 are details.

My invention is described as follows: A housing 1 which has a U-shapedcross section is provided with a partition 2 near one of its ends. Saidpartition is provided with a threaded perforation 3 for the passage of aset screw 4. A notch 5 is cut in the outer end of said housing near thecenter thereof to allow for the adjustment of said set screw 4. A recess9 is cut in the felly 10 to accommodate the said screw. A block 6 whoselower end 7 is curved to conform to the inner surface of said housing 1,has a cross section which is substantially rectangular. Said block isadapted to be adjusted at any point between said partition 2 and the endS of said housing 1. A sutlicient segment is cut out of said felly attwo oppositely disposed points leaving a gap of su'liicient width forthe reception of said block.

It will be seen that in order to make my device practical it isnecessary to cause said set screw 4 to take a downwardly slanting courseso that its outer end may be easily manipulated. Its inner end playsagainst the inner wall of said block. One or more of these devices maybe employed for each wheel, but, however, it. is thought that two willbe most satisfactory, as illustrated in Fig. 1.

Although I have specifically described the construction of thisinvention, yet I may exercise the right to make such modifications oralterations therein as do not depart from the spirit of the claimhereunto appended and which will be obviously necessary in themanufacture and development thereof.

hat I claim as new is:

In a tire tightener the combination with a block of a housing, saidblock having a substantially rectangular cross section, the crosssection of said housing being U-shaped, a partition formed in saidhousing near one of its ends, a set screw passing through said housingslantingly, its inner end playing against said block, substantially asdescribed.

In testimony whereof I atlix my signature, in presence of two witnesses.

GEORGE A. RYAN.
